Historical collection | Part 4: History Forecast Bulk
Posted on 25 Jun 2020
OpenWeather has been providing consistent and accurate data on current weather, forecasts and weather history for many years.
Aiming to simplify the process of obtaining data, we created the Historical Weather Data collection – a flexible and unique combination of our products (including APIs).
This article describes one of these products: History Forecast Bulk.
What we offer
History Forecast Bulk is developed based on modern Big Data technology. Its scope includes such areas as analysis of possible risks associated with the weather (including risks to human health and safety), forecasting the distribution of load in the energy sector, and related areas. History Forecast Bulk is also good for finding out about machine learning models for the Internet of Things data analysis. Its use allows you to create forecasting algorithms for systems such as “smart city” and “smart building”.
History Forecast Bulk is an archive of data on previously made 16-day forecasts collected from 7 October 2017 onwards, and available for any coordinates on the globe. Each forecast is a set of values of the main weather parameters for each period of 16 days in increments of 3 hours. Four model recalculation cycles are available for each day. Each time recalculation happens, a new forecast is generated (it updates the values of weather parameters in the forecast). The forecast update times are 00:00 UTC, 06:00 UTC, 12:00 UTC and 18:00 UTC.

We provide historical forecasts for the main weather parameters: temperature, pressure, wind, clouds, precipitation, humidity and dew point.
